What is normally the most-watched program of the week thus was put on a 48-hour delay for the Peacock, leaving Fox to win Sunday primetime thanks to its own football coverage and halfhour animated comedies.

Fox’s football overrun of the New York Giants-Green Bay Packers game was credited with a 6.4 rating and 19 share among viewers 18-49 and 19.1 million viewers overall, though these numbers are only according to preliminary nationals for Nielsen and will be adjusted. (In addition to the usual variances due to live sports coverage, several East Coast affiliates preempted network broadcasts for local weather coverage.) Postgame show “The OT” (3.8/11, 10.7 million) followed.

NBC ended up with a primetime slate featuring “Football Night in America,” followed by reruns of “Minute to Win It.”

CBS finished second on the night in the demo and first in total viewers, led by originals of “60 Minutes” (1.9/6, 11.8 million) and “Undercover Boss” (1.8/5, 8.4 million) and repeats of “CSI: Miami” (1.4/4, 6.9 million) and “The Mentalist” (1.5/4, 7.3 million).

ABC came in third for the night in 18-49 and in total viewers with its four-hour block of “The Sound of Music” (1.4/4, 6.2 million).

According to ESPN.com, the Eagles and Vikings will play the first NFL game on a Tuesday since 1946.
